The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design deliver a ride quality that once seemed unattainable. After eight generations and more than twenty years of development, it is not only the fastest Tarmac ever made, but it is also the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not win races; it is speed that counts at the finish line. To reach race speed, a specific balance of aerodynamics, lightweight design, stiffness, and compliance is necessary. Our Ride Science Team has determined through race simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on crucial courses. It is a full 16.6 seconds faster over 40 km, 128 seconds quicker on the Milano–Sanremo, and 20 seconds faster on the Tourmalet. The fastest road bike in the world is now paired with the SRAM RED AXS groupset with power measurement—the lightest electronic groupset ever—and a tubeless-ready Roval Rapide CLX II wheelset. All S-Works Tarmac SL8 models feature an ultra-light Roval Rapide cockpit—a sharp design for razor-thin victories.
